After three segv loops caused by /bin/sh segfaulting and the kernel stacktrace filling the file system with log messages, I rebuilt rc6 with Helge's fix. Now I things are better when bash segfaults. However, it drops core so often that the system is unusable for serious work. The problem appears more like a glibc bug than a kernel fault, but it's not clear. Here's one segv: dave@mx3210:/var/log$ dpkg -l libc6 Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad) ||/ Name Version Description +++-==============-==============-============================================ ii libc6 2.7-16 GNU C Library: Shared libraries dave@mx3210:~/gnu/gcc/objdir/libiberty$ gdb -c core /bin/sh GNU gdb (GDB) 6.8.50.20080915-cvs Copyright (C) 2008 Free Software Foundation, Inc.
